Randy,As you say, under the sock is a crossover that divides the signal between the mid and ribbon. This is mid LP (lowpass - ie. it passes the lows and rolls off the mid as frequency increases) and ribbon HP (highpass - ie. it rolls off the ribbon as frequency decreases).
And the external crossover divides the signal between bass and MR/tweeter. This is bass LP (lowpass - ie. it rolls off the bass as frequency increases) and mid HP (highpass - ie. it rolls off the mid as frequency decreases).
"Why does connecting an amp directly to the mid/tweeter section of the speaker cause the fuse to blow?"
Because you are feeding all the bass signal into the mid (which "normally" gets removed by the mid HP section of the external XO). So, far too much current is going through the mid panel ... and the fuse is doing what it's intended to do!! :-))
Just to repeat - you can't passively biamp with the stock external XOs that you have ... so just use one of your amps.
Regards,
Andy
